Patent CA-2313749-A1 (CA)
Inventor: BERGMAN WILLIAM
IPC: B23B51/00
Filed: 2000-07-12
Abstract: The present invention features a self-feeding, wood-boring drill bit. A two-piece bit has a threaded pilot point as part of the shaft. The cutting head has an axial through-bore which is threaded to receive the pilot point, so the two parts are held together in threaded engagement.      An extended bearing surface area or bearing neck is also provided between the cutting head and the shaft, in addition to the threaded joint area. This structure spreads the forces over a large bearing surface, which greatly reduces the opportunity for shaft failure. Two different materials are used for the head and shaft, respectively, so that the head has optimum cutting capabilities and the shaft has optimum strength for transmitting torque and withstanding bending and shear stresses. A long, flexible shaft is welded to the driving end of the cutting head assembly, to provide for drilling operations at a distance from the worker. The cutting head, itself, can be unscrewed and detached from the long, flexible shaft, so that it can be replaced with a new head, when required.
